Hi everyone, I'm a newbie in this forum. Recently the living room of my house have been leaking especially during heavy downpours. After checking the roof condition I realize the wall develop cracks which causes the water sip into the house. So I decided to cover the roof with another roof as shown in the picture. To prevent the rain from dropping into the damage roof. Is this a good method to repair this damage. Need some pointers. Thank you A sketch of the damage area and the propose design is shown in the picture.
